Speaking of Creedence, there's a new documentary on Netflix with their concert at the Royal Albert Hall in London. There really isn't much footage of these guys, and apparently the producers got the rights to this right after the film surfaced. There's a fairly standard band doc that follows their progress, and then you get the full concert. There are no theatrics, it's a very businesslike set with the band pretty much walking out and then standing there and playing. The stage is all but bare, just a drum riser, a couple of Marshall stacks and a bass cabinet. No big PA.
What's striking is that they walk out there and bang out the songs and they sound exactly like the record. No theatrics, no drama. There's maybe two guitar pedals. It's very bare bones, these guys just play their music. It's still pretty cool, because you never get concert footage of CCR. It's truly an artifact of another time.
